I can't think of anything near the exhaust at the front of the car that you might have disturbed & affected the ABS. I think the rear wheel speed sensor wiring runs adjacent to the brake lines on the passenger side, just behind the cill. The N/S front comes up through the wheel arch & only has a short way to go to the ABS module. Cant remember the route taken by the front O/S wheel speed sensor wiring. Worth tracing it all back & doing a visual inspection to check the wiring didn't take a knock & become damaged.
Could all be coincidence as you say. I have a very vague memory of the brake light switch causing an issue for someone else. It's really inaccessible unfortunately (above the brake pedal close to where the steering column goes through the bulkhead). As I said, it's possible to test at the ABS multiplug but you'd need the pinout data. If you're looking to keep the car longer term it's probably worth signing up to a trial with Autodata & downloading all of the wiring diagrams & associated diagnostic info. You have to be careful to cancel it before the trial ends though, otherwise you'll get pulled in to an expensive ongoing subscription. (Some of the suggested diagnostic tests aren't that great as they recommend just testing voltages at the plug & that doesn't tell you how the circuit behaves under load. A corroded or damaged wire hanging on by one strand can still show 12v with no load but would be unable to deliver the current normally required of the circuit).
Hope you get to the bottom of it relatively easily. Cheers for now.
