leon fr tfsi mk2 power

[robcorkhill]

i got a leon FR TFSI mk2. a few weeks ago the car started stuttering and had no power when pushing down on accelerator, in fact felt like it was braking and slowing the car down when foot down and stuttering. been in a VAG car specialist now for a few weeks but the things he tried arent working.
tried high pressure and low pressure fuel pumps, MAF sensor, DV valve, sparkplugs, coil packs, checked pipes for any splits and ECU and as of yet no joy. really struggling to find a solution any help would be appreciated as getting desperate.

PCV valve

Have you got access to VCDS? Could log things like misfire count etc.

bit of an amatuer when it comes to cars. whats VCDS?

 

[MrFwibble]

VCDS is used to diagnose issues on VW group cars. Can be expensive just for one fault, might be best to find a local garage that can do the diags for you.

cheers bud. the garage it at has done that nd he saying it a air to fuel mixture problem but tried just about everything. he got a new wiring on the way so hopefully thats it but not holding my breath

I experienced something similar with my FR a few weeks back, turned out it was the coilpack that needed replacing. Took me 10 minutes to do.

finally got it sorted it was a few things that was the problem. it was the lambda sensor, evap pipe and MAF sensor. tried 1 by 1 and didnt work but put them altogether it seemed to solve the problem
