My IS220D done nothing but mostly fairly short runs and never had any problems with the dpf. When has the car last had a software update from a Lexus dealer? That's a major factor - if it hasn't had one in the last few years I'd recommend paying for it. Use C2 low ash engine oil, clean the egr valve once a year, take it for a motorway run every few weeks and I'd guarantee you will not have any problems..they are a well designed dpf system. That said I agree about the lack of a dpf light. I think you can get techstream from eBay which would monitor what you are looking for - these may be a free legit lite version..if not they are likely a pirate version. I'm not too clued in on Lexus diagnostics.

It wouldnt do any harm to change the air and fuel filter for all that they would cost (if they haven't been done in a while). I also would recommend lots of hard acceleration and high revs (once rolling) for a few weeks to see if it makes any difference. I honestly think my 220d goes well and I think they do not like being driven easy.

@is200newbie - thanks so much for all your help. The car was perfect until it went in to an indie for a service where it had 4 new brake pads replaced. The mechanic mentioned the brakes were seized at the front but managed to free them. Ever since there has been a rattling ovet rough surfaces which completely goes away with the lightest touch of the brake. One mechanic thought it was bushes (after a quick look) a second mechanic had it up on the ramp and said that I needed to get caliper mounts and bolts from lexus. I think it is too much of a coincidence that this noise only started after the pads were replaced and the fact the noise goes away when braking tells me it must be caliper related. A pain in the rear!!! Thanks again

Thanks very much! Sorry im not too mechanically minded so is it that the caliper is seized? It rattles like mad on any type of rough road. Still stops like a train though. Just had brembo pads all round and brake fluid. Mechanic mentioned fronts calipers were seized but managed to unseize them (its the drivers side front)

I've been told I need a new Caliper Mount and bolts which is about £190 including vat!!! Does anyone have any suggestions on what to do as this seems really excessive. Car is an 08 IS220d. Please help!!! Cheers

Hi all, My IS220d was just serviced by an indie at 87k and had brembo pads fitted all round with brake fluid change. The car drives and brakes superbly but since the service I have noticed a rattle from the drivers side suspension when going over any kind of rough road. At first I thought it was drop links but the mechanic said the car was 100% after the service. I had a quick look at the suspension and as far as I could tell everything looked spot on (although im not a mechanic). I then noticed applying any kind of brake pressure stops the rattling when going over bumpy roads. Any ideas? Cheers

I wouldn't worry, they all seem to do it. My replacement engine done it from new and I checked about 4 220ds on the lexus sales line and they all had evidence of spotting. As long as it's not spraying all over the engine bay and loosing lots of coolant it should be fine.

My 220d is the same, it's been fairly trouble free but all wee things at once recently

No worries, cheers might invest in that android diagnostic, can't go wrong for £2.99 in the play store

@The Dreamer - good stuff, what software do you use? Pm if you want.

That said, the D-CAT system has a 5th injector, which operates when the ECU detects a partial blockage of the dpf, so as long as the engine is at operating temp and there is plenty of diesel in the tank, the D-CAT system should sort itself out, regardless of revs. Running it at high revs would do no harm though.

@Matus - I take it you are turning on the forced regeneration option in the software then taking it for a run? In this case what you are saying is correct, you don't need a high rev run as the software is intervening to force a generation. That said for anyone that doesn't have the software, high revs will help get the car nice and hot which is always a good thing. Head lexus mechanic told me at operating temp - 2,500rpm in 4th gear is perfect for helping with a regeneration.

Aye, AFAIK c2 and c3 have the same mid saps 0.8% ash content, the only difference bring a very slight fuel economy requirement difference. I'm the C3 wouldn't do any harm to the 220, but I thought I may as well stick with the C2 as advised by lexus themselves. I used Millers which is great value and is very well regarded. But that GM stuff is incredible value, if I had a 250 I wouldn't hesitate to use it. I would be amazed if there was any real world difference in fuel economy between C2/C3.

That oil is the bargain of the decade, you'd pay that for 4 litres of Castrol Edge! I'd happily use it myself only the diesel needs a C2 spec oil. Good luck, let us know how you get on.
