Booked the Cerb for its Mot, annoyingly it needs a new handbrake cable putting on it, which I have the parts for, also a large bang has suddenly developed when hitting bumps from the back of the car.

I did some research on what could be causing the noise, could be rear diff bush I have concluded, had a look under it to see if the mount was broken but it looks fine, would it bang if mealy the actual bush is perished/worn? Cannot see anything else wrong.

I've booked it into Kerridges Needham Market, first time using them so fingers crossed they do a good job!

Could be the ARB rear drop links, both of mine went over time. Diff bushes would show up more on gear changes and sudden power on/off whereas drop link noises show up best when one side gets loaded or unloaded suddenly.

Had the call today after the Mot test, seems my Cerb has failed massively!
With the estimate to repair it, it's going to have to wait a while.
Gutted is an understatement.

I've hired a trailer to get it home, pick it up first thing.
From the call I had today and recalling what was said, the car has a rear anti roll bar mount broken, excess movement on a track rod end joint, the emissions are to high ( something like 1.5 on odd bank), the fuel cap gas git is not sealing, and something to do with the front wheel having damage on it ( think something rubbed on the inside of the rim once, I know about it and it don't rub against anything), also for some reason the mot was done before the handbrake cable (which it was booked in for) was replaced, so it obviously failed on that as well.

It had a 12k service at 46k and just done a 6k service less then 500 miles ago ( car has 52k on the clock).

Hopefully it won't be as bad as you think

That does on the face of it sound quite a bit but in reality not so bad.

Fuel cap gasket is a cheap and easy fix.

Rear ARB, many people just disconnect the drop links and tie the bar up out the way, not an MOT issue then. If it has cracked where the mounting arms meet the main chassis tubes then it is a bugger to get to and is really a body lift to repair, but the thin metal "u" brackets that the bushes sit in also fail and are a quick, easy and cheap fix.

Track rod end £16+vat http://www.racetechdirect.co.uk/tvr-track-rod-ends...

Emissions could be a faulty CAT if so £265+ vat If not then a faulty Lamda would make the car run rich and fail emissions but it would also run very badly.

Front wheel needs looking at but £100 to get it refurbished if it needs it.

Good luck with it:-)

Can do a new 4.2 cat for £100 plus carriage if needed

Got the car home this morning after hiring a trailer from a local firm.
That is just the bracket broken off the arb, so shouldn't cost the earth to sort.

A reason for fail is also 'the rear brake recording little or no effort', how are the front and rear brakes linked? Is it not just a brake balance valve?

Cause for concern is the emissions, they are so high, the car starts and runs very well, no smoke etc, having had in the past Austec racing map the engine, along with the recent service a natural idle test gave a reading of 5.781, the limit is 0.500!
Both lambda tests failed at 1.632 and 1.565.

Was a few other minor fails such as front plate to small and washer pipes come off.

Thanks as always for the advise given here

No brake bias valve as far as I am aware, check the pads for wear and then bleed through, unless both calipers are seized then there is little else that can be wrong and if it had a recent service at a garage I would throw it straight back at the them questioning why they let it out with near enough no back brakes.

If the car runs OK I would think that maybe the cats are at fault, it does have cats in it doesn't it?

As I mentioned earlier I would be more concerned how the service was carried out if things have failed so quickly. Take it back and let the garage take it to their MOT garage.

With the lambda that far out, and indicating a very lean mix, I'd be tempted to check for exhaust leaks. If excess o2 is being let in the exhaust system that'd cause the high lambda.

That would be a fail as would be removing it altogether, providing of course the tester knows what he is looking at.

Mine passed for years with the rear ARB tied up out the way, I liked the way it drove without the ARB connected.

The car is fitted with cats, so maybe they are faulty.
It was serviced 500 odd miles ago, this was however end of summer last year, since it's been in a carcoon so no corrosion etc, it's roughly 7 months ago so a bit long to take it back having a moan.

I am in shock of how many areas it failed on, the car is a nice well looked after example, and looking through the history always has been.

Think my plan will be to repair the arb and other very minor fails, then take it to Austec and get them to check the engine settings/cats.

My car has cat boxes for MOT but only one has anything inside. Suppose I'm saying just because the cat boxes are there doesn't mean they have anything in them.

Bit of an update on my mot problems!

After I removed the car from the dealer I took it to, I set about sorting the issues out on it myself!
I got a set of 4 axel stands and two low level jacks, got the car in the air and set to work.

The handbrake cable had snapped on the short link to the handbrake itself, I had all the parts to replace the whole lot, so I replaced all of it including shoes and springs, set it up and works well now.
Tested the rear brakes, sat someone in the car pushing the brake while I observed the pistons, discovered they worked fine, unsure why it failed when tested! None the less I gave them a good clean and lubed them .

Rear arb bracket had broke ( which had caused the banging), got two new brackets and bushes fitted, again quite easy to do with the car on the stands.

I was recommended taking the car to STR8SIX for the engine check ( thank you, you know who you are) and mot, which I did.
Hiring a car transporter for the day I set off to Oxfordshire, wasn't to easy loading the car but none the less got it on in the end! Turned up after closing hours but still the guys there had time for me and treated me well.
When I started the car to get it off the lorry it was agreed it was running well, reports have now come back the car passed the mot, emissions are fine with no work required, result !

Only thing which is now left to do is get the time to go pick the car up and enjoy summer with it, can't wait!
