Toyota Avensis 2.0 d4d 2001- Lack of power, turbo not working? #

Posted by Padraig Ward on August 22, 2010, 6:44 pm

Year of Manufacture *: 2001
( Optional ) Engine Code or CC: 1cd-ftv

hello,
i have a car coming in for some time now complaining of same problem, ie, LACK OF POWER. seems like the turbo is not working right, you can feel a surge very slightly in the high 2000 revs, it's very sluggish when taking off, also there is a serious engine judder when accelerating at about 60 mile per hour. Checked wheels and balance, all suspension, could this judder be flywheel or clutch related.
thanks

Hi Padraig,
So what tests have you done so that we can rule them out?

so far i hadn't done anything more than service it, clean the air meter check for leaking pipes and disconnected connectors, i thought the customer was imagining it till i drove a similar d4d with similar mileage the other day and then noticed the difference. no codes are showing up on the scanner. i have it booked back in to clean the egr valve and exhaust sensors etc for this tuesday.

as for the judder in the engine i have ruled out all suspension, drives, joints and wheel/tyre problems. it had a seized front caliper a few months back which had been driven that way for a while so my fear is that the extra strain has done some amage to the clutch/flywheel.

I wouldnt mention the exhaust sensor to the customer in case he goes elsewhere for a second opinion!!
With these I would monitor MAF & Map reading and tee in a pressure gauge to the wastegate port on the turbo, see are you getting air flow & boost and if the ecu sees this.

problem still ongoing. only noticed last weekend that the rod from wastegate actuator was stuck/seized. got it moving some, the car seems bit livlier but not up to standard. slight juudder still from engine. no fault codes showing past or present. if wastegate wasn't opening proper would the fuel mix be affected as in too much air.

Hi Padraig, one of the first things to do is as Ray suggested, and "Tee" into the boost side of things and record what is happening.

Regards mark.

PS, With regard to your last question, if you work out why the turbo is there, and how it achieves what it does then you should be able to answer your own question.
