Hi I own a 1999bit uk turbo. I have fault codes 23two and 32. I no these are maf and lambda sensor. I changed maf yesterday but fault is still there. It has lost all power. Has any one else came across this problem and could lambda cause loss in power . Dan

 

The lambda may cause the problem as it senses the AFR. If it's not working correctly your fuelling will be wrong. However before you spend any more money I suggest you spend some time checking for any air leaks or exhaust leaks.

 

Im not really mechanically minded where should I look etc.

 

If thats the case then get it to a local specialist and let them look at it because it will save you money in the long run, and drive it VERY slowly until then.

 

As above drive off boost as long as this persisits.

It MAY be in LIMP mode now, do a search for how to reset the ecu.

Right dis connected battery earlier cleaned maf and all connectors near this. Re scanned ecu no faults. Took out for drive and was boosting fine. Took home re scanned ecu no faults detected?
