Ok so this S5 n/a I am picking up, the owner told me sometimes when its hot the car doesnt want to start right away does this mean low compression? or is that a worst case issue. I think engine might have some carbon build up the owner was a older female that would only drive the car a day or two a week.

could be a TON of things...

leaking injectors was a S4 problem? can I rule that out

Lol, I'm going w/ low compression



I just dont think a car that has "hot start" issues that is completely stock would be anything simple to fix... i mean, the injectors could be BAD, but dunno...



I like my low compression answer better...

How many miles on the engine?



Certainly could be compression, but I like the leaky injector theory. The injectors don't need to be "bad", they just need to be a little dirty.

108k

I wouldn't assume low compression with that mileage, unless the engine was overheated or otherwise abused.

I think its the injectors, it wouldnt start again. so I pulled a spark plug and it was covered in fuel!

not to thread jack but i have a similar problem with my s4 TII with 100k miles. i have new secondaries and cleaned primaries and i have the same problem. checked the compression and its 100psi front and 80psi rear. think its compression?

just bring the car to 3k before shutting it off
