Hello there!
Picked up my first T4 2.5 (AJT engine) just over a week ago, just got back from a week in Scotland in it. Not my first VW though, had a few of those, currently running a 91 Golf Mk2 GTD as well. Thought I'd join the appropriate forum, or should that be 'best forum...'?
I got it from some guys in Taunton who deal in them- the jury's still out on them though as there were/are a few niggles with it. I'm not going to bore you all with them but one has me a little concerned....
The van starts and runs okay, just chucked a double dose of fuel system cleaner in it for luck, in my own experience they DO make a difference but I know everyone has an opinion about them. The issue is that when it revs past 3,000 rpm it suffers a sudden dip in power, from which it never recovers until the engine is stopped and restarted, once this is done it is usually okay. It's a pain on the motorway especially when it really struggles up even fairly gentle inclines, and there were a few of those in Scotland.....
When I picked it up the guy/salesman said that they had plugged it into a VW computer and it had detected an open circuit on the MAF sensor so it was changed (for a recon Bosch unit by the looks of it). They also said that the previous owner had complained of a lack of power but they had corrected the pump timing and it apparently fixed it.
Does anyone have an idea what this might be? Surely it can't be the MAF again, if it was there would be low power all the time? it seems possible that it has always had a power issue and nothing has cured it.
It has been a working van in it's previous life and I was wondering if some kind of 'anti-abuse' device was fitted to stop drivers nailing it everywhere and the first owners forgot to remove it when they sold it on?
Cheers for any thoughts on it!
