When it fails, the truck either won’t start, runs badly, or throws fault codes that won’t clear. It’s also the part people replace when they want a different map, because the TD5 ECU can be reprogrammed.

Why they fail. The TD5 ECU lives under the seat, which is a bad place for electronics. Water gets in. The seat box leaks, the drain holes block, and the ECU sits in the puddle. Once water gets inside the casing, the board corrodes and the faults start. Sometimes it’s intermittent, which is the worst kind, because the truck cuts out and then starts fine for a week. Other times it just dies. If you’ve had water in the footwell or under the seat, that’s usually the cause.

A few things to check before you buy:

• Part number. TD5 ECUs came in different versions across the years, and they aren’t all interchangeable. Match the number on your old unit.

• Model and year. Defender and Discovery TD5 ECUs are not the same. Confirm which one this is.

• Whether it’s been remapped. If it has, ask what map and whether it suits your setup. A map for a standard truck won’t suit one with a bigger intercooler.

• Condition. Look at the casing for water damage, corrosion on the pins, and any signs it’s been open.

• Security. TD5 ECUs are pair to the vehicle in some setups. Ask whether this one needs coding to your truck.

• What’s included. Check whether it comes with the mounting bracket and connectors.

Fitting is straightforward. It’s a plug in unit under the seat. The tricky part is coding, if your setup needs it. Not every TD5 does, but some do, and you don’t want to find out after you’ve paid. Ask before you buy.

One honest note. Before you replace the ECU, check the wiring and the earths. A lot of TD5 faults that look like ECU failure are actually a bad earth or a corroded connector. It’s cheaper to check that first than to buy a unit you didn’t need.

Also worth doing. Once you’ve got a working ECU, sort out why the old one got wet. New seals on the seat box, clear the drain holes, and check the windscreen seal. Otherwise the replacement ends up in the same puddle.
