sorry, forgot to mention, I did try the Radweld type 'fix', but it didn't work. Maybe a different brand would have worked, but I doubt it, the speed it was leaking out.

Sorry for the extremely long time it has taken me to reply, but I blocked the site for some reason. Back now though!! Leak was defo in the heater matrix as I've isolated it (by re-routing the pipework leadinginto the cabin back onto itself!) Hey presto, no more leak, or heating :( Sadly, the CEL and TRC OFF lights are now flashing at me all the time, and the car sounds like it's misfiring. I read somewhere on the site where someone cleaned the MAF to solve this problem, although I'm not sure how the MAF could influence the TRC, but it is wiggly-amps after all!! I have recently changed the air filter from a really crudded up one, so maybe I need to look at this. Question: Where is it, and anyone have photos? I would pull the codes, but I work from 0600 to 1730 every day so don't get chance to get to a garage very often, and don't have the necessary kit myself. There was a write-up frm the person, but they had an after market air filter, which I don't. Thanks again guys.

No rises in temp. The oil level was a bit low, not below the min mark, but low, so I put the light down to that. Yes, there was a sweet smell. If the leak is in the heater matrix, will keeping the temp set to cold minimise fluid loss? Where is the heater matrix located? As for a code read, I've not got the kit to do so.

Hi guys. I've had the 200 back on the road for 3 weeks now without a major snag until last Thursday. While driving home from work, the oil light came on, so I stopped at a garage and checked it. Nothing too major, so I decided to wait until I got home, let the thing cool down, then top up. No snags. While in there, I spotted the coolant level was a bit low, so I topped up the expansion tank. Again, no immediate problems. I'd almost gotten home (having driven about 50 miles since stopping) when suddenly the screen misted up and I could smell warm, wet rubber. Turning up the heat only made things worse, but aircon on full cold cleared it. I was only a mile or so from home so decided to keep going and inspect it during daylight. Following day, I checked the fluid and it was low, so topped it up by parking uphill, and filling the rad until it overflowed. Left it running for a while and nothing untowards happened. As I'm new to Lexus, I put it down to a Lexus '-ism'. Just driven it now and as I started it up, there was a sloshing type sound. After a minute or two that stopped, so I figured maybe there was some air in the system and it had cleared itself, but after about 5 minutes driving the car misted up again, plus the check engine light is now flashing. I've looked and can't see any obvious leakage, but there's nothing left in the expansion tank. Any ideas where the fluid could be going?

They did! Both front and rear offside.

Looking at images it appears that the upper ball joint is held in place by a circlip. Is that correct? I need to check on the car to see if it's the upper or lower joint that's failed too. I think you're right though, replacing the whole arm may be a bit costly!!

Just noticed my reply never actually posted!! Ruddy mobile :megaangry: I don't tend to get my parts from eBay, I prefer to use my local motorfactor tbh. I know where to go back to if I have a problem You don't happen to have the OEM part number for an offside suspension arm do you? I figure it'll be the same as the Probe (Mazda built) in that it's easier to replace the whole suspension arm rather than try to replace just the ball joint) Thanks for the info about the brakes, I'll see if I can find an MOT place that will road test them rather than using the machine. On that note, does it make any difference if the TC or Snow settings are enabled/disabled? I'm not planning on putting the car back on the road for another month or so as it's been sat for a few months already, so I've got time to strip all the callipers down anyway.

Hi folks. I've recently bought an MOT failed IS 200 sport off a mate. He's relocating and is getting a new company car so he didn't want to spend money fixing it up to take with him. Anyway, it failed on ball joint and uneven brake efficiency. I've owned and modified Ford Probes for many years so I'm quite experienced but was Just wondering if there is anything I need to know specific to Lexus. Any advice gratefully received.
