After getting a bill for £542 for replacing the EGR and MAF sensors the car got worse. It would tick over but wouldn't rev. I bit the bullet and took it to Lexus last Thursday. With the bank Holidays and stuff I gave them a call on Tuesday. They said that they thought that it was the high pressure fuel. Even they resorted to using the internet they told me.
The pump was £1300 and it was engine out to fit it. I said that After already spending almost a £1000 that they needed to be more certain that just 'thinking' that it's the pump! They agreed to cut the labour rate down to £65 per hour from their claimed £110.00 and also discounted the pump. I also asked them to do an ECU reflashes/updates.
I collected the car this morning after settling the bill for £1939.73 and not only did it run and rev properly, it felt like a different car. The turbo lag from 1st to second was so much better, you caould actually crawl on to a roundabout in second or even 3rd gear. You can put it in 4th at 40mph and it will immediately accelerate.
I've learned a lesson here. I wish I'd gone to Lexus in the first place. Their computer can shut off the injectors one at a time and get fuel pump readings etc The specialist did as much as he could before I took it to Lexus but the next step was to send the injectors off and the pumps for testing at £50 each. That would have been another £300 plus vat down the drain.
Lexus confirmed that my car did have the modded cat fitted and as stated they did the latest ECU update for the vehicle.
I'm poor but I'm happy to have the car back.
Thank you for those that offered advice and I hope that by my leaving the results of my experience that it may assist someone in the future.
Cheers
Robby
Hello Guys,
I am a newbie to this forum, and although my car is not a lexus - i do have the T180 engine in a corolla verso. I am also experiencing similar problems to Robbies original post, having serious turbolag issues that come and go as they please. I just wanted to add to this post after reading all about there being no diagnostic codes recorded in Robbies situation. If the high pressure fuel pump was becoming blocked/restricted, then i would have expected a diagnostic code to be flagged. The common fuel rail has a pressure/temperature sensor installed in it. Surely if the pump performance was decreasing, the pressure in the fuel rail was not being pressurised to the correct pressure (1600-1800 bar) all of the time - THIS WOULD BE REGISTERED AS A FAULT AND AN ERROR CODE STORED!? Maybe even to the extent that the MIL (engine) lamp would be illuminated.
I am still trying to get to the bottom of my problem - going to start with the MAF sensor and air intake and work from there.
