Hello All, I am new to the forum and have a problem with my Patrol and am hoping someone on the forum will be able to help out with advice to solve it. I purchased my Patrol new in 2003 and have been very happy with it for over 200,000kms. Over this time I have had the glow plugs replaced, the intercooler and the upper and lower hoses and fan belt. All of which I was happy to have done. Over the last 6 months and whilst towing a caravan the Patrol has been losing power when negotiating hills (slight of otherwise). It has done this on several occasions (not all). The loss of power is gradual going from a speed of about 80-90kph down to the low 40's notwithstanding that I have the accelerator fully depressed. If I release the accelerator and reapply it the revs pick up for a very short period before losing power again. I have been unable to get the Patrol to replicate the symptoms when taking it to a dealer (twice) (even going for a drive with a tech with the van on and going up some hills). They say without experiencing the issue they cannot properly diagnose the problem. In trying to seek an answer myself I have come across this forum. I noted that one subscriber "Benton" in 2009 had a a similar problem and advice was given to him and this related to carbon deposits in the turbo. I was wondering if Benton is still out there and had the issue resolved successfully. I would very much like to hear the outcome and any other advice to assist in this issue. Thanks, DustyM.
