Hi All,
2002 FL1 TD4 54k used for short trips for a few years.
I bought the above a few days ago on mileage and body condition. It is spotless outside and very good inside....BUT..it has done the school run and not much else for a few years.
I suspected it needed a good service as it was a bit sluggish. once on the motorway it was fine and got me home in time for the pub.
Now I have been reading the forum for the last few days and gleaned a lot of info from old posts, but an a bit confused over one issue.
The FL is slow to take off but fine when it reaches 2750rpm. It goes to 90mph with no problem [allegedly]
I have read the posts about the MAF sensor so tried it disconnected, pulls well from 1200rpm, foot down and engine rattles and pulls away...as it should.
Cleaned the MAF sensor and refitted...no change, slow pull aways with little response to a floored accelerator. No rattle just a slooow increase in speed.
Bought a new Bosch unit, fitted and still no change. Read reports of it needing to 'bed in and the ECU to catch up' so drove for 50 miles mixed motorway and local roads. No change. Still flat.
SO..my question.....if it is another component at fault, WHY does it run fine with the MAF disconnected?
I realise I have a long way to go to diagnose this fault but how does it behave OK with the MAF disconnected if it is not a MAF problem?
I have an EGR removal kit and a PCV upgrade on order and I will clean the inlet path as best I can at the same time.
Also, unrelated....the tailgate window regulator was repaired in 2010. I ran it up and down about three times and it fell to the floor! Now propped up with a bit of wood and the repair kit ordered from ebay. Are these any good?
Thanks
Andy
