Missing and backfire

Everyone thinks these computers tell you the cause. They read fault codes, that is the effect. I find the cause.

To do a compression test on a car takes no time at all. And knowing the s54, a compression test is a good idea.

+1 Nice to hear some people do other checks rather than rely on what the PC say's

Bosch for the new one and going to do the others in the next couple of weeks.

I think I have 6 bosch coils here, probably done 50 miles max, thats 5 0 not 50k.

If anyone wants spares

Read what Lawsy posted.

Damn right you do. Not pointless at all, especially with this engine and the use it gets.

I was refering to cars in general not just the CSL, in general terms if a car has a misfire and a coil resolves the issue then a compression test is pretty pointless. Ok I see your point re-csl's and common problems but I think any car any of the time to check compressions whenever a car has a misfire is a little excessive.

It is always nice to know that everything is good inside too, compression give's advance warning if something is starting to go wrong

Stops customers returning unhappy.

Sometimes, poor compression, coolant blowing out spark, can cause plug to fail and coil to fail prematurely. You replace coil and plug, all seems well for a short period. Customer returns unhappy with "its exactly the same as it was before", which creates a feeling of dissatifaction.

2 minutes to check compression whilst coil and plug is out = no brainer.

And because we are on the csl register, talking about a misfire on a csl, and I know how many csl have poor compression due to iminent failing hg, I was talking about the csl.

As mentioned, it's the work of moments. I'd rather have peace of mind.

Quite right. Pro-active maintenance works.

Read above and take note of those with more than a little experience.
