Help I'm struggling with engine issues.

[MarkChrisian]

Hi guys I'm new around here. Just bought a 2006 IS 220 D with 103000 on the clock and I already have problems. It started with engine light on and check vsc plus traction off. My friend who owns a same car cleaned my Erg valve and we erased the error. After few days I had another error. Something  about a 5th injector issue but after erasing it it never came back. Now I have a p2002 code and another engine light on with both check vsc and traction off. It comes up even if I'm stationary just reving up to 2000-3000. I even took my friends egr valve and put it in mine (since he has no issues) and after erasing all the errors they still come in. I'm so tired looking through the net. Any help would be appreciated.

First thing I'd check if I had multiple warning messages is the state of the 12v Battery. A low Battery can trigger various error messages.

If the 12v Battery is good then it's a case of getting the codes read.

[MarkChrisian]

Don't you think that the Battery would make an error on dash at the start not during the drive? And why is it always engine with traction and vsc? O wanted to buy a new EGR valve but since I checked my friends one who's supposed to be ok it's the same issue. What else is there to check if it comes to exhaust system?

P2002 isn't related to the EGR, it is a fault related with the DPNR catalytic converter - either the pressure is inconsistent between the front and rear, or the temperature isn't rising as expected when the ECU add more fuel during regeneration. The following are the potential areas where the problem may be, in order of most likely to least.

1. DPNR catalytic converter (Manifold converter sub-assembly)
2. Differential pressure sensor
3. Differential pressure sensor vacuum hose is clogged
4. Blockage in vacuum transmitting pipe sub-assembly
5. Exhaust gas temperature sensor
6. Fuel injector
7. Exhaust fuel addition injector
8. Turbocharger sub-assembly
9. Exhaust gas leaks in TOYOTA D-CAT
10. Mass air flow meter
11. ECM

Wow. This is too much for a simple guy like me. Basically without a professional help it's not something you can do in your spare time.

There is a reason why everyone on this forum will tell you to stay away from the 220d if you can get the 250..similar economy, much nicer gearbox and mainly no engine issues.

Any chance you can return the car if it's from a dealer? You have 30 days.

Nope private purchase. I wanted a diesel and to be fair I haven't checked that those 220d are not the most economical. But previously I had Subaru Impreza WRX so the difference is visible 🙂. Besides my friend has the exact same model and no issues. So I thought it would be a good deal. Anyway I'm going to take it to some specialist and hopefully the issue will be resolved.

Economy is not the main issue here, the reliability is... I think IS220d does get about what one would expect from loaded "luxury" car that weights 1600kg, but reliability is not what one would expect from Lexus.

Don't want to suggest anything, but some owners are less willing to share negatives of their car ownership and focuses on positives more. IS220d without issues does not sound quite right. We had some owners on the forum in the past who were very diligent with maintenance e.g. cleaning EGR every 5000 miles and who were doing long distance driving only... sure in that case they didn't have major problems, but that is because of combination of favourable driving routine and staying on top of any maintenance and doing all preventative maintenance. 

Once IS220d gets to the certain point (and I would argue that any of the ones sold for less than £2000 are way way past that point) they just become uneconomical repairs.

Two things mate. Firstly as long as I don't have to spend as much as for my scooby I'll be happy. Secondly I never heard any car to be reliable. I had VW's Mazda's Honda's BMW's and I always had to invest in it. The only issue I have with the Lex is that when it comes to fixing the fails that I have I can't do it by myself as with other cars I owned.

[MarkChrisian]

Just an update. Cleaned DPF £340 and it's fine. For now. Was told that the best option was to mapp the damn thing and I'm thinking about it. What's you thoughts? Any opinions on mapping the ECU?

Lexus IS250 is really reliable, apart of AC compressor failing because I didn't maintain it properly I only ever did basic maintenance and consumables e.g. tyres all the way to 200k miles.

ECU cannot be mapped (should not be confused with hacked) and even if it could, it would be illegal. So you looking at £1000 +6 points for "mapping out" DPF and potentially much more if your insurance is invalidated and you admit of doing it yourself (+£3,000 and 6 points for insurance and £10,000 for altering emissions outside of "proper use").

Do people do it? Yes - many people do it, but finally we starting to see crack down on this. Most of the time you just get your MOT stripped at the spot, or just failed, but in case of accidents insurance will always try to not to pay for whatever reasons. Removing or "mapping" put DPF makes it no longer road legal and all insurance contracts are based on assumption that car is road legal. And on top of all financial problems and MOT it is kind of immoral, because diesel cars are heavy polluters, especially when emissions systems are removed. 

And finally, apart of this - it is against forum rules to discuss, so if you have any other issue with the car nobody will be able to help you with anything as they ultimately come back down to illegal modification.

[MarkChrisian]

So I cannot ask any more questions because I asked about something I have no idea about? How was I supposed to know what is legal and not. I have no idea about mapping and ECU and any electronic stuff. This was just a question about something I was told about. Sorry that I don't know the law in this country regarding modifications. All you could say is "mate is not legal and not recommended". I think this topic is closed.

No problem with asking any question. Regarding the DPF, it would be illegal to remove it and use your vehicle on the road so we can only advise you don’t go down the route. Here’s some more info on the subject.

If you search these forums there are several historical discussion with advise on how to stop the DPF from clogging but it can just come down to usage - if you never to long runs to allow regeneration it will eventually clog so you will need to do periodic cleaning.

Ok let me sum this piece ok kaku of a car. I thought I'm buying a reliable diesel car that will help me reduce some cost of driving and I will not have to worry about too many things. Now this car is not an economical one to start with and then you have to drive it in such a way that it doesn't help with the mpg and then it's going to clog once in a while and you can't do anything about it other then send it to specialist pay loads of money for something that will happen again. Now I drive this kaku and I'm worried every time if any working light will pop on. Who designed this? Someone who hated driving and cars? Is this an accurate description?

Yeah sorry mate but your summary is accurate. Diesel cars in general are only economical if you do regular long distances. If you use your car occasionally and at low speeds just around the city go for a petrol or hybrid they will be fairly reliable and provide decent economy. 

I had a mercedes e class and got rid of it because of ULEZ but was always worried about the dpf and egr clogging up or turbo failing. I use my car mostly in the city for short distances so got a hybrid now and am happier. Given my low use i fill up once in 3 months. With the merc it was every month as every weekend i would do an unnecessary motorway run just to keep the dpf clean.
