Hi peeps, was after some advice really.
I have just bought an B6 A4 1.9TDI Quattro which came with the MTM upgrade already fitted.
Problem is, its rubbish! No power or torque from low down and then the usual 'PD kick' around 2.5k....only difference from the std map being that power band is shorter than the std map!!
And if im honest, the power that you do get aint that great. I had a PD130 Bora a few years back and even in std form it was alot smoother and quicker.
I have just done a full service using OEM ginuine VAG parts abnd still no difference! Thought it maybe the MAF but a quick look on VAGcom showed the target and actual readings pretty damn close.
The car is in later this week for a cambelt, waterpump and aux belt replacement and I have asked the tech to check out all the pipework under the bonnet in case of a vacuum leak..but I still think this crappy upgrade is to blame for the poor performance.
How would I go about removing this unit? any ideas? As I would love to get it custom coded so I can have my old 'diesel power' back... :weight_lift2:
