Hello VW folks,
After many years of owning & driving other cars, I now have a Mk4 Golf TDI 2003 1.9pd. The car is fabulous to drive other a frustrating limp mode issue every time I start it up and initially drive, it hesitates to go and has a weird noise.. It makes makes a whirring, motor, solenoid type of noise when its moving, if I stop it stops; only when its moving. The noise seems to be coming from in front of the passenger area. It directly affects the power - when its making the noise, the car almost goes into limp mode with definitely reduced power, if I put my foot down, it hesitates but eventually goes and once doing 40-50 mph - no (aidible ) noise and no further problem - only at slower speeds and especially with a cold engine. The glowplug light is flashing and the 'traction control' light comes on, flashes but eventually just stays on.
After driving a mile or so, the 2 lights are still lit but there is no further problem with the car and it drives / behaves perfectly, even at slower speeds - once its warmed up.
As I am unfamiliar with this engine I recorded a wee vid on my phone & you can just hear the sound about 8 through to 10 seconds in.
It comes and goes and clearly is directly associated to the fuel system and or ecu. Someone had suggested it was the 'N75' - so I bought a new one & replaced it but it has made no difference.
After 20-30 seconds of starting the car, I get the message 'Engine Workshop' come up and then it goes away. EML not lit. I used my ELM 327 Bluetooth connector and Torque Pro but there were no available fault codes (to Torque Pro). I suspect that if I managed to get a VAG.com lead and software I might get to the bottom of it but I haven't gone that far yet. I would like to get this at some point & would also appreciate advice on where and what to buy.
I do wonder whether it might be the ABS pump? - but why would it affect the power..and why would there not be an ABS bulb lit up..?
Any help would be gratefully recieved
