Hi people just after a bit of advise,
I`ve got a 2006 A4 Avant TDI (170), on a long trip last week, the glow plug light started flashing, then after about 15 miles the engine light came on, can`t remember which light is emissions and which is engine management, but anyway, slight loss of power not going over 3000 RPM, so I pulled over switched her off and let her have a breather, then got full power back with just the engine light on.
So booked her in to an independent garage for diagnostics, they said loads of faults came up so they cleared them, and because on test they couldn`t get the light to come back on, to drive it and as soon as the light comes back on, bring it straight back, after seven days the glow plug light started flashing again so I took it back again.
They said two faults have come up, throttle body, and MAF meter, and that they thought it was the throttle body, £400 notes plus labour, and if that didn`t cure it, they`d have to then replace the MAF meter.
When I asked how much the MAF meter was they said about the same price, but they were 80% sure it was the throttle body.
My dilemma is this, I used to be a car mechanic years ago with not such advanced electronics on the motors back then, but I priced up the parts at a motor factors, Bosch parts that are fitted to my motor, just doesn`t come in a Audi box, £150 plus VAT for the throttle body, £58 plus VAT for the MAF meter, they had the MAF on the shelf so I bought it and fitted it, drove it like a joyrider for an hour and it`s mint, my thinking and how I used to diagnose problems back then was go for the cheapest option first, but the guy in the garage wasn`t having any of it.
I`ve got it booked in for the throttle body change on Thursday, (this was before I priced up the MAF and fitted it), with my £150 part, do you think this guy was just trying to have my pants down, or just made the wrong educated guess, or is it that its not fixed and the light may come back on, don`t want to replace any parts if it`s not necessary, the guy seemed really nice and he didn`t charge me for the two diagnostic plug in he did, don`t know if I should see how it goes or take it back to him, I`d fit it myself but I`ve read you have to align the throttle body with diagnostics, any thoughts would be helpful.
