I just wanted to write a quick note to thank Kev B for his initial suggestion of using Car Surgeon all that time back.
I encountered the hideous engine management light issue and the DPF code only last week and found this site to be the most informative on the matter. I called Imran at Car Surgeon on Thursday, who sorted the problem out within 3 hours on Friday. EGR valve cleaned and DPF regenerated.
He also said that running the car at high revs to induce regeneration once limp-home mode is activated is a piece of folklore which wasn't helping us Lexus drivers at all. Apparently there was a VW Passat with which you could have some success trying this option but it never worked for a Lexus and he wished people knew more about this. All we are likely to do with our cars is melt our EGR valves!
A very nice, no-nonsense guy, clearly very knowledgeable, reliable and helpful, even though he did tell me Lexus diesel engines are all "sh1te"! Sometimes I guess the truth hurts!
He told me, now that the car is fixed, to keep it in 5th gear if (like me) you drive between 70 and 80mph on the motorway, and to avoid supermarket fuel. Was well worth the trip to and from Birmingham (from Herts).
To update you all, the price is now £309 for the two-part process. Not only did Imran have to put £15 of diesel in (for which he only charged me £10), but he even sent me a text later in the day to see if everything was ok. He was so confident in his work that he said if the problem arises again within 3 months he would be regenerate the DPF for free. Top man, very highly recommended indeed. And no, we're not related! :)
Just thought this page might benefit from the update.
Cheers all!
