Ali, my mate has told me about the Wolverhampton place so I'm ringing them tomorrow along with your Nuneaton link (that's handy but looks like MX5 specialist).

These Mazda 6s are great cars but like most they have inherent problems. The cam chain is a weakness which surprised me - I'd rather have a chain than a belt.

If the car didn't have warning lights you would drive it unaware of any issues. It goes like stink and is very economic! However there is a DPF light shouting at you and the dreaed engine symbol! Thank god 240Zs don't have them!

I'm convinced the DPF is a bum-steer and just related to service/oil intervals etc On Friday I had a guy do a diagnostic check. He found the DPF issues but also cam/crank sync issues which points to cam-chain wear. OK it is a known problem so we now have a positive diagnosis.

He ran a forced Regeneration cycle for 30 mins which in theory clears the DPF. The heat from the exhaust was fightening. Anyway that didn't clear the DPF light but there are solutions on the internet on how to do this - ground a 'pin' and press the acc pedal 10 times. Modern cars

So do we run the car and pray or change the cam-chain. We change the cam chain but close to £1000 is a big hit - they don't mention this in the sales-rooms do they!

The dealer wants £75 plus vat to re-diagnose the problem which is robbery! I've said if they diagnose it and it says the cam-chain is ok fine we'll pay the £75 plus vat. If they come back and say yes you were right it does need changing then I'm not happy paying.

I've also fitted a new boot-release switch which seized up. A known problem and now updated - £50 a switch!

Rob depending on the mileage on the car depends if its worth it or not I suspect its quite high, one thing for sure though the chain is stretched/worn which throws the cam/crank sync out, just done a search on my subscribed faults and fixes data and yes stretched chain brings up the dpf light another thing that's for sure it will break transit 2.4 duratorq diesels do break at 180,000 miles but can go for 230,000 plenty o timing chain kits on ebay for the transits

I'm sure you have seen this Rob but I think there is a chain for the oil pump as well, so if you do get it done have both done I can't see it in this kit

TT

Hmmm tough call Rob! I'd be inclined to grit your teeth and change it if you plan to keep the car for a few years.

Take the dash cluster out, take the dpf bulb out and sell it.

Jon, remind me to never buy a car from you

Rob Not a hijack here but your not alone' had a 2009 tdci focus in today that had fault code p2585 looked into it and it has a wet dpf system fitted any way long story short these little babys have a nice little plastic tank fitted next to the fuel tank above the rear axle which contains eolys fluid, nasty stuff with lots of warnings, holds around 3 litres and injects a tiny squirt into the fuel tank when the little magnet on the fuel filler lid triggers the reed switch when you fill up, seems a bit vague to me as gives the same dose with a fivers worth or a full fill, anyway the car is on 60,000 and is supposed to have the eolys fluid refilled at 30,000 miles and so on also works on a counter which needs resetting after filling, problem with this one the cheapish small cast pump on the side of the tank that's open to all the elements was corroded badly damp and not working, new tank and pump £450, fluid £120, axle components removed and fitting, diagnostics and reset £150 total £720

Yep, that 59 Chevy with V6 is becoming more attractive every day!

Anyway daughter's car is currently having the chain replaced - pick it up tomorrow.

I read about those 'wet' systems and wondered how reliable they were and what about when the car has ventured into owner servicing.

To top it all my lads Pug 306 broke it's clutch cable last Thursday when he was with me 50 miles from home! Got it home when the rush-hour was over and replaced it the next day. It has a really weak plastic 'fulcrum' that fits over the pedal. That had snapped and main dealer didn't stock the cable. When I said according to the internet it's a common fault he said haven't sold one for 7 years - no wonder, he hasn't got any to sell

Just got to sort Lee's Golf now - Engine Management light on. Last time it was one of the 6 coil packs ANOTHER VERY COMMON WEAKNESS!
