As in the subject title old girl fail her medical today. I believe she hasn't  got much wrong with her but would welcome some advise as to the best way to overcome the niggles.


1) Offside front steering box insecure. Chap said bolt/nut missing. ??
2) Exhaust emissions excessive (7.3.D.4)

MOT Tester says i could possibly reduce the emissions by fitting a new cat but that seems rather an excessive and expensive option to me.

Thanks in advance for any advise.

Bet he could sell you one, too.

Steering box bolts need tightening/replacing as required.

As for emissions, let the tank run low, then...

New plugs
New airfilter
2 cans of wynns injector cleaner plus a full tank of Shell V power
Rag the living dailights out of it
Refill with V power
Rebook MoT and make sure car is HOT when it goes in

Might be lambda sensors .... be worth getting the ecu read to see if any codes stored for them, imo

My mig was a swine for emissions every m.o.t.the last 3 years was told the same...new cat.....I use shell v.power  all the time because it is such a better fuel for the emissions and as for the rest take  taxi al advice it should do the job for you.....I know it works for my car  ...

[SteveAvfc.]

Thanks for your help guys.

That steering box one.....there is a single stud on the Omega box that has no and never had a nut on it.....

Is your cat setup an original one or cheapo aftermarket?

I reckon there is a scam by MOT garages fitting pattern cats unnecessarily. On 2.0 Omegas the OE cats cost £880 plus VAT from Vx, and should last 100,000 to 150,000 miles. Yet garages fail them and sell punters pattern cats costing £100 or so, which last about 1 year. Last year I bought two 2.2 low mileage Omegas, confidently expecting to get original cats with them. No chance. They both came with Timken pattern cats. I understand that original cats have a good scrap value (full of platinum gauze) but that pattern cats have no scrap value.

In an MOT it is important that the tester gets the cat good and hot before final test. I suspect some do not bother. I always watch my cars being tested. My daughter took a 2.0 for test in Enfield, London, and it failed on emissions, new cat recommended. I told her to bring it back to Somerset, take back a different car, and I took her car to my local MOT shop. After a warm up, it passed.

On the 4 pots, its often a failed flexi that results in a pattern part being fitted.

In this case its a much better option to weld a new flexi in!

You need to read the results from the emissions test before doing anything else. That is the start of a proper, accurate  and therefore effective diagnosis.

My old 2.0 failed on emissions , they threw a can of cat clean in then italian tune up and it sailed through 

[SteveAvfc.]

Completed all the tasks but still failed. Cat is shot got one from Eurocarparts £88.00 cheap enough so fairly happy.
