So on the back of some of my old threads, my brothers 1.9 100bhp TDI blew a few month ago. He was told it was the turbo that had gone, so rather than paying £1,500 to VW, the mechanic got the part number & did an eBay search & gave my brother the listing ID.
£300 or so later & my brother was providing this bloke a new turbo.
Had that fitted but it didn't solve anything really. Black smoke coming out even days/weeks later.
It went back & the bloke blanked off the EGR which helped a lot but didn't fix the issue.
Anyway, i think the EGR has been totally blanked now. New drive belt & tensioner fitted for the whining.
New AFM fitted & my brother fitted a new MAP sensor today which hasn't sorted the issue.
Basically when he's pulling away in 1st there's hesitation. He has his foot down & it's struggling past 2.5k revs. Switch into 2nd & everything is good to go - boost, normality.
He says he has to give the accelerator pedal a double blip at times when setting off to try & get going. Once he's out of 1st he's good, though he has said that this current turbo, even when working, doesn't feel as fast as the old turbo before it blew. I guess that's what over £1000 of turbo does then?!
Anyway, the mechanic said if it isn't the MAP sensor then he's tried everything he can think of. Any idea what can be the cause here?
