307 HDi MOT fail, horn & smoke test

Post by clydeowenp »

Well didn't expect to be back quite so soon! Took 307 to Halfords for an MOT with it's nice new fuse box installed and it failed. Checked discs & pads, ground off lip from discs and measured the thickness, rear 7.4mm (min 7mm) and front 23mm (min 24mm). I intend to replace pads & discs but no time to get, at a reasonable price, and fit before MOT. All freed up and chewed up screws replaced so fitting new ones should be quick & simple when they arrive. Tester failed rear saying they're excessively worn and seriously weakened, but these are above minimum thickness. Passed front with an advisory saying worn but not seriously weakened, but these are below minimum thickness! They quoted almost £350 for rear pads & discs but got them on ebay for £28, also ordered fronts at £35, thought that was good, under £65 for pads & discs all round! Don't think they were bad enough to fail but what do I know, difficult to win an argument against these people.
It also failed on dust cover on drop link and track rod end but brought an assortment on ebay. Failed on horn not working, works when lock button pressed on remote when already locked, anyone know why? Main dealer couldn't tell me. Asked them about the horn not working and was told there's a comm link or something in the steering wheel which, if faulty could be expensive. Problem is it means removing the air bag to get to it, I've read the procedure in the Haynes Manual but it looks like a long job. Any ideas or suggestions which avoid taking it all apart would be appreciated.
A more worrying problem is the smoke test readings which are: 1) 3.04 2) 4.11 3) 2.92 4) 3.03 5) 3.10 6) 3.40 zero drift 0.21 Average 3.06, pass is 3.00 so only just failed. I would expect the readings to fall with each acceleration but these are up & down all over the place!
Mileage is now 123785, I got several old MOT test certificates with the car results were; 2016 @ 119720 miles 0.32, 2015 @ 118349 0.07, 2013 @ 114584 0.04, 2012 @ 121193 0.11. Annual mileage since 2010 has dropped from 4 - 5000 miles to about 1000 - 1500 miles in 2018. Air filter doesn't look very old and certainly isn't dirty or clogged, will check air ducting tomorrow for splits and kinks.
I had a fault code come up which put the car in limp mode, wrote it down this time, P0221 followed by refer to manufacturers service manual. I've seen this before but after several start cycles it cleared itself. looked it up on line and it says throttle position sensor, B circuit range / performance. Came up again day of the MOT so cleared it as they wouldn't be able to do a smoke test with it in limp mode. Checked and cleared this with my Autel FR704, could this be related to the high smoke readings? Halfords say it's an internal fault on the turbocharger and they'll fit a new one for £726.37, NO CHANCE!!!!!
I think I've got the Lexia set up correctly but not tried it yet. I think t's going to get a baptism of fire soon to sort this out but I'm really going to need some help as I haven't a clue how to use it and what to check for. Halfords say it's an internal fault on the turbocharger and they'll fit a new one for £726.37, NO CHANCE!!!!!
I got a friend to rev the engine while I watched and the exhaust was clear, could it just need me to thrash the nuts off it down the duel carriageway for a few miles!

Halfords don't do car testing on Ireland but if they did nobody would use them...
Oh buggle

I won't be using them again, only used them cos they were the cheapest. Took my 106 in for an MOT and they drove it onto the ramp so fast it grounded ripping a 2" gash in the sump. Cost them £299 for new sump, fitting and oil, probably more than the car is worth, but at least it saved me the cost of an oil change.
With the 307 I suspect they were trying to generate business. On retest I got the engine red hot and insisted they record the oil temperature, which they didn't on the first test, and it went through on a fast pass at 0.19.
