I think my wastegate rod went to pot today!
Do you guys know if it is now possible to get a wastegate rod replaced
without getting a whole new turbo? I hear that was not possible a couple of years ago, but since things keep getting better all the time ... JP Roberts P.S.: Might be time to upgrade to a k04? Oh, I would be so happy if it were just some piping! |

Re: I think my wastegate rod went to pot today!
Dear HOK,
God knows how I desperately want it to be the inlet hose and I still have some hope it will be. I'll have it checked tomorrow morning, so your opinions are greatly appreciated - given the kind of dealers here one never knows if you might be cheated into buying a new turbo when that was not necessary at all. Symptoms are as follows: Continual observance of warm-up and cooling-down procedures from day 1 of buying the car new. What happened yesterday was some mixed-condition driving: Some 1/2 hour on dual-carriage way, lots of frequent boost because of heavy traffic, avg speed 130 kph. Then some 1/2 h up a mountain pass - non-spirited, some 1/2 h downhill, perfect turbo cool-down. It was only when I was getting home that I went without boost when attempting to overtake in fifth gear. Repeated attempts showed very little or no boost was present. No funny noise whatsoever, emissions seem to be OK, max power restricted to the normal aspirated engine range or at most to stock range - my perception. Engine behaves normal and no lights went on on dashboard but there is only a little - but steady - boost only in the 1,300 to 2,000 rpm range. Fair enough to mention I'd been seeing a small amount of surging under full throttle in 5th gear since day 1 of chipping (from 56k miles to 75k) and always-present pinging at 2,000 rev mid-throttle on slopes. Since the turbo is still spooling, the worst thing might be a broken wastegate rod, but I keep my fingers crossed and hope it's the hose.

If that's the case, then I'd say that it's almost certainly the hose either crushing or a combination of crush and slipping off of the metal pipe (something else that has been observed) If the car feels down on power at odd times, then you might consider replacing the DV. I replaced mine at something like 800-1000 miles with a Forge unit - response was instantly and noticeably better, indicating a failed DV (but without the infamous goose-honk). The hose will get replaced once the car gets back from the body shop (thanks, dear neighbour of mine, for driving into my car when parked on my own driveway..) Best bet for yourself, I think, is to check that the hose is tight at both ends, and maybe consider a DV swap (can't remember the age of your car, so I'm not sure of you have Bosch's latest attempt fitted) IIRC an aftermarket DV should be in the region of GBP 85, and is a 5-10 minute job to swap.

My wife's A2 1.4TDi exhibits a 'goose honk' everytime you open the throttle to pull away from rest. I presume that a TDi has a DV - is it likely that it has failed? The only other possible symptoms I could point at would be less 'go' than I would like below 2000RPM (above that it really takes off), but I assumed that this is standard for a small TDi. Also the fuel consumption is significantly worse than I had expected (average 50.8, according to DIS), and 70mph cruising at around the same value (which doesn't tie in with the official figure of 78.5 extra-urban). I like to think that my driving style is reasonably economic (my RS6 is currently showing 23.4 average on the DIS!).

Did your faulty DV throw a code?

Re: I think my wastegate rod went to pot today!
Problem solved!
It was a faulty wastegate valve connector!

Re: I think my wastegate rod went to pot today!
If the car seems to be running normally without a MIL, check for boost
level with a pressure gauge. More than likely, the MAF has expired. I have replaced the MAF on both TDI's I've serviced. Same sypmtoms, runs fine, no MIL, no boost. The output under load can be checked with the VAG. For that matter, so can boost. On Wed, 15 Oct 2003 13:48:06 +0200, "JP Roberts" <1234@yahoo.com> wrote: >Dear HOK, > >God knows how.............. |

Check whatever it is that JFP is saying first (must confess that I couldn't follow the abbreviations) On a TT (YMMV ;o), the DV is a small chunk of plastic, something like (from memory) 1.5-2 inches in diameter, just "south" of the main inlet hose. The honk is caused by the membrane fluttering when it should be sealing. Makes a big difference to performance (can't remember the MPG, though) HTH H1K |
Re: I think my wastegate rod went to pot today!
As I understand it, JPF's acronyms refer to:
MIL Malfunction Indicator Light or similar. MAF Mass Air Flow sensor TDI Turbo Diesel electronic Injection VAG Volkswagen Aktiensgesellschaft or the Diagnostic tool that Volkswagen Ltd. uses to check on their cars.
