W210 Air con condensor sealant- Is it Ok?

[Veridian]

Hi folks I have a '98 E430 with Climate control - other than the continuing saga of trying to track down a regulator for the blower - been looking for over a year now to no avail so making do with airflow only at 'level 3'

Anyway, I have had leaking aircon for some while now - usual scenario. charge the system up and its fine for around a month or so then fizzles to nothing. Anyway took it into my Indy who reckon its a pinholed Condensor. To replace that c/w Dryer and do a recharge they quote 400+vat!.

Anyway I have bought from ebay an aersol of 'airco seal pro' (from Primalec.com)- around £35 which seals holes in condensors and evaporators etc - effectively you add it to the system and if it comes into contact with moisture as the gas escapes it hardens to seal the hole. I reckon this should work well with my system - though the exam question is that it says should not be used on systems with 'Hermetic Compressors'... Does that inlcude Mercs?!! - Any body had experience of using this stuff?? The primalec website although detailed doesnt seem to cover this.

the age of your car will have a standard electric clutch compressor, never heard or used the stuff so cant help there, most parts depts carry the reg in stock, why cant you find one???

Hi colechelle, no probs re Air con.. As to the Regulator, well, yes you'd think they would but I can assure you they dont! I'm on first name terms with Andy - parts manager at Mercedes World in Weybridge - indeed they initially supplied me with the regulator the IT system said my car had according to my VIN -- only to find that it was the newer version, (with integral HeatSink) and not the older regulator which screws directly onto the blower which has the heat sink moulded ito the aluminium housing of the blower itself. (Apparently Mercedes changed the design as my version proved troublesome).
Im on the books with MercMan in Southampton as its a part which they see lots of demand for but only rarely comes in - There's even a workaround using a Reg from an S class which Im hoping to use. Failing that you need a new blower, & regulator (new type) and mounting kit.. Over £400!!.. hence my search for a workaround.
