A month after I bought my SL320 last July the nearside catalytic converters decided to self destruct and started making an horrendous knocking noise. I replaced these with a new genuine MB item for £685 rather than an ECP special on the basis the original had lasted for 16 years. I asked if I should change the right hand ones at the same time and I was advised if they were fine to leave them so I did.
When I saw a new old stock right hand catalytic converter advertised a couple of months ago for £295 or best offer I offered £240 inc. p&p and got it.
Yesterday on my way back to Suffolk from Hertfordshire you've guessed it there was a catastrophic failure of the right hand cat. This caused cylinders 1-3 to misfire like buggery and I limped home like an ageing Honda Jazz driver for the last 20 miles. I think it must have been silently breaking up for some time, a back pressure check on that side showed 15 psi when the maximum should be 2 psi. So bargain replacement fitted and my car is running better than ever.
