Catalytic converter thefts


Recommended Posts

I think this is mentioned in various places but maybe deserves a thread of its own.

Mother in law had hers nicked last night (2 year old Lexus).

Cheeky bastards used a bottle Jack and angle grinder. We do at least now know that her newly installed double glazing is bloody good.

Thing is, the scumbags know it will be fixed and sat there next week, plump and ready for nicking again.

How, short of a shotgun stakeout, do you stop it happening again and again?

The newspaper article from snacr says a second hand cat converter has a value of about £60. That's what gets me with crime. The economic loss is absolutely huge. Someone has to spend over a grand

There was a post from a chap on our local area Facebook group saying that a gang of four crims did his BMW 1-series last week. Apparently when he opened his front door to see what was going on one of

I think there's a sort of aftermarket cage you can get secured around them.

Do cars run just fine without them?

In which case why not run until a month before MOT is due and do it then?

After all we pay police to stop crime, they don't GAF about this sort of petty theft, far too busy with coivid harrasment [appropriate typo].

We're expected to buy a part and mechanic time, all plus 20% VAT [used to pay police of course] to replace. All to help the environment, society, Greta and other people in general. Isn't it time to stand up and say maggie was right after all, there is no such thing as society, fuck that I'm not cooperating.

There was one nicked a hundred metres from my parents' house last week. What they heard is that the criminals target an area and move on. They're generally professional and not usually local. It isn't likely that they'll be back soon. It is a target rich environment so no need to return to the same spot as burglars used to do to get the replacements.

Because with a massive gap in the middle of the exhaust system it'll sound like a tractor.

Yes. My daughter had the Cat chopped off her Honda Jazz in the staff car park of Basingstoke hospital last summer. My other daughter got an email from Frimley hospital warning of thefts last week. Honda Jazzs are the favourite apparently. 

I would chop the hands off anybody caught stealing Cat converters.

Night vision cameras & this sort of thing?

I know the rozzers have to catch them first, and how it works with heat, and so on...but a thought anyway..

Plod weren't in the least bit interested.

Usual thing - crime number and on your way.

Why the TDI badge?

will the engine start after a cat removal ? would have thought it would error

diesels tend to use base metal convertors and adblue fluid

my honda civic has the cat behind the radiator in the engine bay

Diesels still have a precious metal converter, but they have to have an additional catalyst (base metal) to do nox reduction, they also need a particulate filter and an ammonia slip catalyst. Exhaust systems on diesels are pretty complex.

is wikipedia wrong then ?

Wikipedia is not wrong, but you're only looking at part of the system. 

The first catalyst is an oxidation catalyst (DOC) to convert CO to CO2 (there's probably a wiki article on this step too), this is precious metal, the next step is then SCR to deal with the NOx (the bit in the wiki article). 

In a petrol engine it's different, there is no oxygen but some hydrocarbon left in the exhaust gas so the NOx is used to oxidise the CO and hydrocarbon and no SCR is needed (look up 'three way catalyst' on wiki for this) 

Edit: here you go https://en.m.wikipedia.org/wiki/Catalytic_converter#Diesel_Oxidation_Catalyst
