code 26 & 28
I have just picked my car up after having a custom exhaust fitted, but I am getting a code 26 & 28. Is there a common link to these faults, and is it simply a loose connection after the exhaust was fitted?. I have looked around, but I am not sure what I am looking for.TIA :eek:

#26 Quad Driver Module Number 1
Check EGR, Canister Purge and AIR pump relays with a digital Ohm meter. A resistance of less than 18 ohms indicates a bad relay. If OK, potential ECM failure.
#28 Quad Driver Module Number 2
Air conditioning Clutch relay and/or cooling fan relays. Check with digital Ohm meter, replace if less than 18 Ohms. If relays OK, potential ECM failure.
