cat on a tdi

[tdi-man]

how can you tell if your cat on a 140 tdi is blocked ?

Same as any exhaust blockage. Lack of power,not enough exhaust fumes coming from exhaust. If in doubt just cut the frigging thing out and put a piece of pipe in. Should only cost £50-100 to do.

Should get a warning light in your dis.The you have to drive at about 40mph in third for a couple of miles to burn the carbon off the cat comb.It smells like bakelite.

You must be thinking about a DPF not a cat. No wires connected to a cat and to burn soot out of a cat you drive fast.

The standard cat is free flowing so makes very little difference to exhaust pressure/flow. Changing your back box will lower back pressure and make more difference to the turbo and power then removing the cat.

PD140 engines don`t come with a DPF.
