TheEdge Posted September 11, 2008 Report Share Posted September 11, 2008 Hi all Ive noticed on my R today there is a slight hesitation when changing from 1st to 2nd and/or somestimes 2nd to 3rd gear its not severe just the car seems to be hiccuping, its a mark 4 with 37500 miles so the 40000 mile service isnt far away !! has anyone else had this problem ive heard people mention in the the early days of the Mark 4 R there was a hesitation problem not sure if this is it? just wondered if the spark plugs could be on their way out and need changing, as i remember on my old mark 2 GTI when the weather changed to winter it was stuttering horrendously my mechanic serviced the car and it was fine he changed the sparks etc ? thanks all any advice would be appreciated Link to comment Share on other sites More sharing options...
bazza_g Posted September 11, 2008 Report Share Posted September 11, 2008 How long have you had it? When I had my R32 in 2003 there was the famous "6463" update that solved the hestitation, especially in hot weather Link to comment Share on other sites More sharing options...
TheEdge Posted September 11, 2008 Author Report Share Posted September 11, 2008 Hi mate Ive had it since August 2005 this strange hesitation has only happened as of this week I think apart from that the car is fine!! the car was last services almost 9000 miles ago so it is due soon well January I hope its not anything serious when the service was done in January 2006 their was no mention at VW that they did anything like the 6463 etc Link to comment Share on other sites More sharing options...
Ritey Posted September 12, 2008 Report Share Posted September 12, 2008 If it were me I'd take it to your dealer and simply get them to check the 6463 is applied, if it isn't they should do it free of charge as it was a recognised software update for your car Link to comment Share on other sites More sharing options...
Decked Posted September 12, 2008 Report Share Posted September 12, 2008 Could be a faulty MAF. Have the garage check it out when it goes in. A MAF is about £70-80 IIRC. Link to comment Share on other sites More sharing options...
jimmyp Posted September 15, 2008 Report Share Posted September 15, 2008 Is it a stutter?? if so coil packs maybe?? Link to comment Share on other sites More sharing options...
TheEdge Posted September 15, 2008 Author Report Share Posted September 15, 2008 No mate its not a stutter just a slight delay, I did a 100 mile round trip on the m25 m11 yesterday the car was filled with V power only 2 days ago ive been getting 31MPG driving at average speeds of 70mph no more !!but compared to Tescos super unleaded when i filled last month this is low as only a few weeks ago i was getting 36 MPG ( on Tescos ) driving conditions were similar, I need to check the MAF havent got round to it yet though as im sure if tht was affected my average MPG would be out as well I think ???

bazza_g Posted September 15, 2008 Report Share Posted September 15, 2008 I can't remember ever getting more than 30mpg out of my mk4 R32 Link to comment Share on other sites More sharing options...
mb Posted September 15, 2008 Report Share Posted September 15, 2008 Mine's similar mileage and also has the same "stutter" was gaping holes without the 6463 update... It started after its 1st service (20k) and seems to be almost non-existent on V-Power (30ish avg at 70) I am leaning towards the coilpacks as another car had similar symptoms but a lot worse & were the coilpacks - nothing comes up on vag-com yet so not sure If you get to the bottom of yours at the service please let me know !

macdaddyR32 Posted September 24, 2008 Report Share Posted September 24, 2008 As has been said.... I'd say MAF , If its just appeared then it wont be the 6463 upgrade. Link to comment Share on other sites More sharing options...
Gti_Fly Posted September 24, 2008 Report Share Posted September 24, 2008 if you're getting 30+ mpg on an R32 I'm not suprized the car's stuttering! Take the car for an italian tune up sharpish! Link to comment Share on other sites More sharing options...
mb Posted October 6, 2008 Report Share Posted October 6, 2008 if you're getting 30+ mpg on an R32 I'm not suprized the car's stuttering! Take the car for an italian tune up sharpish! What I said was cruising at 70 I get 30... But followed your advice & put my foot down & was rewarded with a loss of forward motion (as if traction control had cut in) & a flashing orange engine light (which went out after a bit). Vagcom finally had a fault & it looks as if its No 1 Cylinder coil-pack so will post back once I have fitted a new one (VW dealer out of stock so ordered via Vagparts) Link to comment Share on other sites More sharing options...
mb Posted October 9, 2008 Report Share Posted October 9, 2008 Well, replaced the coil today (thanks to Mook for pointing me at the correct cylinder) & on a short drive all the hesitation seemed to have gone so far is best 28.00 have spent on the car ! Bought a spare incase this is the beginning of a pattern... Link to comment Share on other sites More sharing options...
Mook Posted October 9, 2008 Report Share Posted October 9, 2008 Glad you've got it sorted There's no logic to when the coil packs go - they just go. If the car gets hot (e.g. prolonged track usage at full tilt) then they're more prone to go. I went through 3 in one day at Spa last year...

mb Posted October 9, 2008 Report Share Posted October 9, 2008 Cheers ! Do you know if the spark plugs are changed at the 4 year service as it started hesitating after it was serviced at the end of last year & wonder if disturbing the coil to pull the plugs set it off maybe ?

Mook Posted October 9, 2008 Report Share Posted October 9, 2008 Possibly that's what did it. Plugs should be changed every 40K miles, although I changed them every 10K because the car had a hard life. Link to comment Share on other sites More sharing options...
Dan32 Posted October 13, 2008 Report Share Posted October 13, 2008 Mine developed a similar problem after I had owned it for a bit. The 6463 update cured it. Dealers still don't like to admit it exists as it ties up a senior tech for couple of hours flashing the software. Check its had the update and then get them to hook up computer to it as could be multitude of things, including lambda sensors or even the cats on their way out as well as everything else mentioned before. So, need to consider: 6463 (it should have this regardless of whether dealer says it needs it or not) MAF Coilpacks Lambda sensor in exhaust Cats Link to comment Share on other sites More sharing options...
mb Posted October 13, 2008 Report Share Posted October 13, 2008 Hi Dan, Has had 6463 as one of the ones really affected by it & so far 1 new coil pack & that's it. At the moment I am doing battle with the locking wheel bolts which seem to have been over-tightened when it was serviced. Tried a jack against a wall pushing a "star" wheel brace into the bolt/key with an axle stand underneath and all it did was distort the locking key. Fortunately the bolt itself is OK so have ordered a new key from McGard - thought afterwards would have been best to have driven/braked a bit first to get the wheels warmed up. How stupid an idea is removing all the other bolts & driving (gently) around Sainsbury's car park - I think it is the "cup" that siezes rather than the actual thread ?

Dan32 Posted October 14, 2008 Report Share Posted October 14, 2008 I know my brothers car got a locking wheel nut seized on and when I couldn't get it off, and broke the key and the nut itself, to put on the spare after a puncture, the AA man put in a blob of metal weld epoxy in the key and put the key onto the nut, let it set and then used that to break the nut free. It worked but obviously the wheel nut was toast. I'd try and get some penetrating spray in there first to see if that helps before removing all the other nuts as this will probably add too much load to it.

mb Posted October 14, 2008 Report Share Posted October 14, 2008 Thanks - I did wonder about super gluing the new lock in to further resist it camming out - should have ordered 2 keys then if the new key doesn't work can just give it to Michedevers when it needs new tyres and say its their problem, as fortunately the key rather than the bolt itself chews up...

Gti_Fly Posted October 15, 2008 Report Share Posted October 15, 2008 I recently had a battle with my McGards. The original key just fell apart in the end, had to order a new key from McGard, took about 4days to come from Germany. Great service. Anyway, you should try over tightening the existing 4 nuts, this will 'ease' pressure off the locking nut slightly, giving you slightly more chance of getting it off But definatly order a replacement key from McGard anyway, they cost about £15 delivered.

mb Posted October 17, 2008 Report Share Posted October 17, 2008 Thanks some good tips - have been out for a couple of days but the new key was here when I got back. So will over-tighten the bolts, get the wheels good & hot & then see how I fare ! Link to comment Share on other sites More sharing options...
mb Posted October 18, 2008 Report Share Posted October 18, 2008 Well success actually wasn't too bad with an unmolested key ! I spoke with McGard who were really helpful & explained the keys are designed to take 2.5 x the recommended torque before they let go & they said over-tightening was a big problem for them. They actually recommended using an airgun the remove the bolts but not to do them up... The bolts aren't in bad shape now, the key looks as if it has suffered a bit though so not sure if to clean them up & reuse them, buy a new set of McGards, go with the VW bolts or just put 4 "proper" bolts in on the grounds that most R32s will have wheel locks...

Gti_Fly Posted October 18, 2008 Report Share Posted October 18, 2008 Mate for the sake of £30, I'd buy a new set. It's not a great deal of money, and atleast you know they are brand new, so failure will be less likely (now you've learnt things the hardway) I went back to using the VW ones for now. My car is always garaged anyway, so I'm gonna take the risk. Glad you sorted them though Link to comment Share on other sites More sharing options...
mb Posted October 20, 2008 Report Share Posted October 20, 2008 Your right, whilst the car is parked in safe places 99% of the time I just paid 1/2 that for a puncture repair so even if they are not 100% guaranteed I would be very upset if my wheels got taken... McGard asked for some feedback so will see if can blag a new set out of them as the "stars" are a bit worn now - especially the one that was really stuck on & order a spare key straight away. Looking at them I think the problem is corrosion on the seat of the bolt/wheel so I think some copperslip on the backs of the bolts would help - they were quite adamant you shouldn't grease the threads as leads to over-tightening - although looking at the threads some corrosion def took place there too...
