Smudge Posted December 8, 2003 Report Share Posted December 8, 2003 Driving into London today, M25 to M4 sliproad & cruising nicely. I look down to check my speedo as I'm getting onto the M4 & my ESP light is on (IE I'm supposed to have turned it off?? ). Well I didn't touch the buton, and I'm riding solo. So I push my ESP button but this does nothing. Hmm. Next option is to come off a jct early (I always catch the lights here). So, stop at lights, handbrake on, engine off. Start her up again & the ESP lights now cleared. Weird! If I remember correctly S4Dreamer experienced the same with his car on the drive home?? Well it didn't do it again today, and I didn't notice any difference in the cars handling, but then I'm not really giving her much yet. My worry is, I previously had the joy of having a Vectra as a Co. Car & I had a warning light linked to traction control. Vauxhall took the car in as they claimed traction control, anti-lock brakes & the airbag are all connected, and herefore a fault can be little scary. Anyone got any simlar experiences or know of the links between the cars "senses"?? Cheers Al. PS - I can't help but feel I'm looking for problems. HELP!!!!

Simon690 Posted December 8, 2003 Report Share Posted December 8, 2003 This has happened to me, but only once in 2K miles. EPC(?) flashed on and then the ESP light stayed on until I restarted the engine. As it has only happened once I have put it down as just a glitch. I think S4dreamer saw this happen on his way home from the stealer with his new car Quote Link to comment Share on other sites More sharing options...
shao_khan Posted December 8, 2003 Report Share Posted December 8, 2003 ESP light used to come on on my TT from time to time - it is designed to idicate some minor fault...sometimes, not suggesting your new new car has a minor fault or anything.

Smudge Posted December 8, 2003 Author Report Share Posted December 8, 2003 I'm not worrying about it tOo much. She's running really nicely at the mo. Still wrapped in cotton wool! Got a tiny stone chip on the bonnet already & some feckin gritter trashed me at some traffic lights tonight!!!!! I was sat waiting on red whilst he went past on my left in a filter lane. Car in front, car behind. I was freaking out!!!!! Can't move, can't move arrrrrgggghh!!!! Sounded horrendous but I couldn't see any additional chips. FECKIN' GRITTERS!!!!!!!!!

shao_khan Posted December 8, 2003 Report Share Posted December 8, 2003 After your post here I have since read that ESP light staying on means you should drive the car for 96 hours or it might break. Quote Link to comment Share on other sites More sharing options...

s4dreamer Posted December 9, 2003 Report Share Posted December 9, 2003 Yep, happened to me just the once on the drive home after collecting the car and I haven't had it happen since (now at nearly 1k miles). Quote Link to comment Share on other sites More sharing options...

ChrisR32 Posted December 9, 2003 Report Share Posted December 9, 2003 It's happened to me once in 30,000 miles in the TT but not in the R32! I've done about 3200 miles in it so far. I don't know whether this is any use but if i go over a bump or hit a small hole going anything over about 10 mph the ESP light goes mad!!

BAsically if it comes on and stays on you should have the car checked at a dealer - replacing the MAF is common place because VW use such [email protected] parts and I have had loads fail on different VWs in the past.

[/ QUOTE ] fecking ell... that was quick... seems to me like its going to take awhile for VW to get a revised version if it ends up like the Audi Coilpack issue! What are the symptoms of a MAF sensor failure on a N/A engine as on a turbo-charged engine the turbo has a loss for air boost its very noticeble.

I'm calm at the mo to be honest. But there's a slight vibration from those alarm bells!! They said the AMM is running a bit high (about 25% above ave) whatever that means!!?? Anyone any ideas? I'm just waiting for a call back from Ridgeways Senior Tech to see what they want to do. Fingers crossed, 'cos she's running fine (in comparision at lemon!). Will keep you posted.

Mollox Posted December 9, 2003 Report Share Posted December 9, 2003 OK this is all S3 biased so forgive me. The basic componentry in question is the same though. The MAF (Mass Airflow Sensor) is a charged platiunum wire that sits in your induction tube. This is the bit where I pull back and science kicks in but basically it works out how much air is passing over it because either its temperature or charge varies or both. Science out of the way – its important. This is where your whole mixture gets determined from so its critical to most VAG engines. It is of course reassuring to see that VAG fit such reliable parts in this critical function. Using a Vag-Com (I cant remember the block #) you can ‘read’ the MAF. Typically on the 1.8T engines problems arose because the MAF reading was too low, leading to a drop in performance as less air=less fuel in the bible according to MAF. Its ironic therefore – if your MAF is reading high then you should get more fuel in there and either mental performance or it really not seeming quite right. Maybe there were failsafes in place. Quite what the link between MAF and ESP light is I still don’t understand but from what I gather this light is often used to determine MAF problems. It’s a completely non-serviceable part (apart from cleaning – which a dealer won’t do), its also model and engine specific apparently, which helps Audi keep the price for an S3 MAF at around £210. I too had an ESP light stay on on my S3. The first thing to remember is that if this light won’t go out – you DO NOT have ESP until it does go out. One to bear in mind now that outside temp is hovering above zero Mine turned out to be a ‘failed’ Haldex ECU and ESP Lateral Acceleration Sensor which came in at around £1,600….it was really obvious I had a problem though as I was suddenly introduced to wheelspin, torquesteer, and uber nervous handling! All for a pesky light! Quote Link to comment Share on other sites More sharing options...
Smudge Posted December 9, 2003 Author Report Share Posted December 9, 2003 Cheers Inigo Makes a little more sense now, though was kinda what I understood it to be. VW explained to me that the ESP light would come on if any fault is logged on the ECU. Also, VW refer to the MAF as AMM (Air mass meter) though it's gotta be the same thing?? My MAF Reading has come out at 4.5 g/s (whatever? ) and they said it should be around 3.2 -3.5 g/s. Strange thing is the engine feels lovely and smooth at the mo. So don't know what effect it is having, if any. My paranoia is that it's going to damage the engine in some way & that I'll be back to square one, & I really don't want to go back there again!!

Mollox Posted December 10, 2003 Report Share Posted December 10, 2003 I made it all up Strange cos when we used to log my MAF readings on the S3 it was giving around 150-200 under a decent load. I was sure that was g/s too...mind yoo 200g of AIR per second is a lot of AIR! Maybe its that much more powerful ! hahaha Or would that be the incredible effect of the Turbo of Might? Should be there tomorrow Quote Link to comment Share on other sites More sharing options...
