Failed mot today, on an oxygen sensor. Back on Thursday for a retest.

It has failed its emissions test at MOT on CO excessivelyhigh something like about 5.5 on petrol (it was difficult last year to getthrough), HC were under the 200mark. It has LPG and that runs OK andits emissions are fine on LPG which is what I suspected. It blew a cylinder head gasket about 8...

Hi I must be mad but bought another MOT fail 1997 V8, it was very cheap and with LPG and a RPI rebuilt engine...It may just live to fight another day! Okay using my Nanocom under SPS1 it reports " The harness check resistor is measuring open circuit." , well I checked the passenger airbag...

I seem to have a multitude of problems and am struggling to fix them faster than they occur :sad: The car is a 1998 2.5 Diesel with 123k miles. Question 1. I have been experiencing the death shake at around 50 to 60 mph. I changed all 4 shocks and upgraded the steering damper and things have...

Hi Guys, New to the forums and could really use some advice. My dad has just been for an MOT of his 4L Petrol/LPG 1998 Range Rover P38 and has failed on a few things. The garage said the last time they tried to do the suspension works without the "specialist tool" they nearly killed someone so...

MOT time of year again - I think the only thing it might fail on is the exhaust - when it stops raining I'll get under and check it all out, but I don't *think* it's blowing, yet. Decided to replace it with a stainless one anyway (before, or soon after the MOT...) So - We don't want a "sports"...

Noticed the boot of the steering box track rod end was breaking down about 5 years ago, but put it on my "To Do" list. Now, deep into that list, I just replaced the whole bar, and its fellow connecting bar behind the front wheels. as all of the boots were dry/perished. As a relocated Brit, I...

Hi all, I am after some advise / other people experiences with reference to MOT failure with my P38 on emissions. I have taken it to a local specialist who has the diagnostic equipment to talk to it, It has no faults stored or present in GEMS The CO2 at idle is between 7 and 8% leaning off...

Well the old girl passed her MOT today and very pleased I was too:razz:. However it was noted on the advisory part that the rubbers on both lower Ball Joints are perishing and probably won't make it through the next MOT. (OK on the day etc....). I spoke to the tester and he told me the joints...

I am new to this forum and need some help with the running on my recently acquired P38. The vehicle is a 1998 4.0lt petrol/lpg. At the first test it was running very rough on tick over and the hydrocarbons went through the roof, so I was informed. So I set about the obvious and changed the spark...

Just a post to say i have successfully overhauled my valve block - yes! In the end it was a split diaphragm valve. Quote from the kids " Mr Green is UP!!!" :) So big thank you to this site for being here :) Failed MoT on a)over revving on idle, b) airbag light fault, c) too much play on...

I took my 4.6 HSE for an MOT it passed, but when I set off home it would not rev pass 1500rpm, so turned back to the garage to see if they could find the problem. The garage owner claimed it was running well when he took it up the road to do a brake test (he only had a rolling road brake tester...

I own a L322 2005 vogue (BMW 4.4). It has failed its MOT today on the offside (drivers) dipped beam pattern. A few weeks ago that bulb stopped working and was replaced (with a Lucas Xenon bulb). At the time the local garage commented the beam pattern was unusual but swapping the bulb with the...

Hi, Just wondering if anyone knows the best course of investigation to take when encountering 'headlight levellling ecu not responding' and, if associated, 'light check module. dimmer potentiometer open circuit' faults. I previously came across this when clearing a suspension inactive fault...

Dear All, The new M.O.T regulations mean that brake or airbag messages or lights being on are an immediate fail. As mine are on from a long past low voltage error I'm wondering are there any ways to get them to go away without having to use the comms port. My car for some reason I've not been...

Hi, First post so all help appreciated. My P38 2000 Thor engined 4.6 Holland & Holland LPG equipped failed its mot on high hydro carbons both on LPG and petrol. Original LPG test reading was circa 9000! Checked air filter - like new. Absolute thrashed it down a Mway, retested on gas had dropped...
