Flashing glow plug light and no accellerator!!
Hi guys just wondering if anyone can help me. I have a 54 plate 1.9 tdi 130 and three weeks ago i was driving home from work when out of the blue the glow plug light started flashing on the dash, and i lost all accelleration. The engine continued to run fine so i could limp it off the main road and then towed it back to my mates workshop.
After a load of research and also speaking with a guy at VW we ran diagnostics on it (snap on not vagcom), and got some error codes for the Throttle position sensor. we then did a load more research before ordering a new peddle assembly complete with the sensor and fitted it the next day.
I thought the problem was solved and all was good up until yesterday when the poxy thing done it again, exactly the same flashing light and no accellerator.
I turned the engine off whilst rolling , then back on again and it cleared for another few minutes before doing it again, and managed to get it home by repeating this process.
The car then drove fine today on the 30 mile trip to work, no problems at all????
Ive now been googling and searching this forum which in turn made me think it may be water in the plenum chamber so ive spent the best part of two hours checking that only to find its bone dry and theres no blockages.
Therefore I am now stumped, my mate with the diagnostic machine is away for 3 weeks so i am unable to scan it again, although i would assume it would be the same error codes.
Has any one got any ideas before i bite the bullet and book it in at Audi??
Any help would be much appreciated.
