PD Turbo removal

Recommended Posts

I have guess that the VNT on my 150PD Golf has jammed as I have been advised that I have an over boost error log causing limp mode when I try to hold the revs evenly at 4000 rpm in 4th & 5th the car drops into limp mode. I have changed the MAP, MAF and N75 valve. The only other thing to check I guess is the vacuum pipes to and from the turbo unless anybody has any other suggestions. So if it is not the vacuum pipe it means the turbo needs a refurb.

I’m a bit of an amateur dab hand with the spanners so the question is should I try and remove the turbo myself to send it for refurb, or is this a job for the professionals? And if I do try and do it what are the hazards? Will I need any special tools or to get any gaskets or seals replacement parts for reassembly?

It's a pig to get the turbo off with the engine in place. Lots (and lots) of patience. If you find a VW specialist who charges a reasonable hourly rate, you'll save yourself a shed-load of time and trouble. They should also be able to offer you a recon'd turbo.

Might be a bit late here, don't want to hijack your thread - but may stop you spending money if it isn't the turbo...

My 150PD had similar problems for ages. If you kept your foot down after pootling along in traffic for a while, it was hesitant & finally logged an overboost fault, going into limp home mode.

Anyway - to cut a long & very dull story short it turns out that one of the tappets wore through and has been wearing away the camshaft. shocked.gif One tappet had worn through completely & 2 others look pitted. camshaft had indeed worn down.

Replacement camshaft & tappets/lifters at £600 + labour will cure it apparently sportifs2.gif

When my garage phoned VW parts they said it was a known fault when the wrong oil was used with the 150 engine. The oil in my sump was apparently thick, but I've only used VW or Millers oils. Wish I knew what the local VW specialist used when he serviced it 18 months ago...

Just thought it might avoid you spending ££serious on a recon turbo if it isn't the issue.

The PD150 is indeed well known for chewing camshafts and tappets. Specifically the 150 aswell. And I doubt it has anything to do with incorrect oil, so don't worry too much about that. It's just VW's way of getting out of a costly situation.

Might be worth any 150 owners having a peek under the cover at about the 50k miles mark, see if theirs is being affected.

Well update guys, my car died just over 2 weeks ago. The cam shaft had eaten the follower, it had also destroyed the valve and required a refurb head. Also the turbo was stuffed with the vanes jammed solid and the bearings full of shrapnel from the follower. Joy..... This all from a car with a full VAG service history and 65K on the clock.

The car has had a lengthy vist at autopool and is now back to full health though my wallet isn't!!!!! Hats off to the guys their for the top quality work and getting my car back on the road.

I agree with Rustynuts if you have a 150pd pop the rocker cover and check your followers before it is too late.
