2003 e500: check engine light on..me theres a leak (fumes) from it

Customer Question

I have an 2003 e500 with a check engine light on. Took it to the dealer and they told me there's a leak (fumes) from it. They diagnosed it as needing a shut off valve replacement. Given the cost of thiis 1> does this sound correct and 2> can I take it to a competent mechanic and have it fixed? What parts are involved? (of that was 3!)

Hi Mandrus Man, did they give you the fault codes? Were they referring to the canister shut off valve?

No I didn't have the presence of mind to ask but they were refering to the canister sut off valve
Expert:  Marty replied 5 years ago.
Ok, the codes aren't that critical as long as you know they were referring to the canister shut off valve. The shut off valve and the regeneration valve are common problems. We often replace both if one fails in order to avoid comebacks. Msrp on the shut off valve is $169 and on the regeneration valve is $65. I would estimate 1.5 hours labor to replace the shut off valve and 0.5 hours labor to replace the regeneration valve. I would also add 1.0 hours labor to scan and erase faults and retest the system. Any Mercedes repair shop with the proper scan tool should be able to do the job.Let me know if you have any questions.

Marty;
What is the life of the canister? Is it cheaper/simpler to replace whole unit with valves?

Expert:  Marty replied 5 years ago.
Hi AB, I don't see too many canister failures (if any at all). The complete canister is about $450.00. I wouldn't replace it right now.
